News Synopsis

According to ISRO, Aditya L1, India's first solar mission, is expected to launch in the third quarter of 2022. Initially, the project was authorized and the satellite was scheduled to be launched from Sriharikota in 2019-2020. However, that date was pushed back because of the COVID-19 epidemic.

It will assist scientists in studying cosmic sources like pulsars and supernovas and will be launched using a small satellite launch vehicle. The temperature of the Sun's outermost layers, known as the corona, is more than a million degrees Kelvin, which is significantly higher than the solar disc's temperature of about 6000K. Solar physicists are still baffled as to how the corona may reach such extreme temperatures. With Xposat, they will be able to look at how polarized celestial events are. The SSLV, which is still in development, will carry the load of launching it. Additions to Aditya- L1 will allow it to make observations of the chromosphere and photosphere. Particle payloads will investigate the Sun's particle flow when it reaches the L1 orbit, and the magnetometer payload will monitor the fluctuation in magnetic field strength in the L1 halo orbit. These payloads will have to be placed far enough away from the Earth's magnetic field to be of any service in low Earth orbit.

ISRO and numerous Indian research institutes worked together on Aditya-design. L1 mission's spacecraft will be transported 1.5 million kilometers from Earth to L1 Lagrangian, a position between the Earth and the Sun thought to be excellent for studying different phenomena without interference by eclipses. The PSLV-C56 is expected to carry it to orbit.
